i To all 207mm t may concern Be it known that 1 GEORGE VVALTHER, a 'f'citizen ofthe Unitedr States, residing at Day,

l ton, in'the county of Montgomery and State Q of'()hio,ha've inventedcertain new-.and use-4 ful Improvements in Wheels', of whlch the'following isa specification, reference being had therein to theaccompanying-drawing.

f ,This invention relates to steel wheels of 'the general type showninPatent #1,120,256 issued ytome December 8, 1914:, and has for ""filts'particular Object to provide an improved wheel designed especially toObtain the maxi--A "@mmv 'in strength and 'minimum in welght.

l I v "It is an Object in the present invention to provide a wheelhaving channeled spokes, of any suitable shape, preferably of the I-beamshape,and to so relate the spokes to the hub and rim of the wheel thatwheely shocks or stresses will be evenly distributed and -absorbed to aconsiderable extent through the wheel.

It is a further object to provide a wheel of the general characterdescribed self-cleaning in design, z', c., a construction that will notreadily retain loose soil and carry it'with the wheel in the operationthereof.

Also, as in my .earlier inventions, it is an object in the presentinvention to provide a wheel construction well adapted to molding o1`erations, the wheels being cast, preferably, in steel of any suitablecomposition, so that the loss or waste due to defective castings will beminimized. i

In the accom panying draw1ngs:`- Figure 1 is a s1de elevation, partly 1nsection, of the wheel, and

Fig. 2 is va cross sectional View taken substantially centrally throughthe wheel.

As here shown the wheel consists of the usual elements of hub, spokesand rim, the hub being substantially of the same construction as thewheel of the patent referred to, consisting of the oppositcly disposedhub i extensions 1 and 2 and an intermediate enlarged central portion orspoke-section 3. The hub consists further of inwardly eX- tendingflanges 4 and 5 forming an annular chamber 6 within the hub bearingraperture.

The spokes 7, as here shown, are of I-beam formation in cross section,the anges 8 8 thereof curving laterally to meet the corresponding curvedportions of the adjacent resiliency with the GnOi-GETWALTH-Enor DAYTON,OHIO, AssI'GNORUTO THE DAYTON vSTEEL FoUNDRYj COMPANY, or DAYTON, OHIO,IA OORPORATIONOF OHIO. f

spokes. Theianges lare tapered or linclined toward each other outwardlyfrom the hubs to a point indicated by van 4imaginary line followingtheeurVe ofy thespreadingends of the fianges. l

The'rim o r felly of the wheel consists of the oppositely disposed rims10-10' joined together'attheir inner' edges by a series of annularchannels'or depressions 12, the outer walls of which form a series ofangular shaped ribs 13 disposed between the spokes and having theirOpposite facesrinclined toward the outer edges of the rims 10-10,l thusforming a self-cleaning surface of the inner side of the rms between thespokes. Longitudinally adjacent the spokes transverse cross bars 141 aredisposed between the rims 1()'-10.

Whilethe I-beam shape is the preferred form of the spokes, othersuitable channel forms may b'e employed with a rim construction of thecharacter described, and l do not wish to be limited therefore totheexact construction and arralvlgement shown except as defined andcomprehended in the appended claims. y i

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. A metal wheel consisting of a' hollow hub, channeled spokes and arim, said spokes being tapered outwardly from the hub, and having aportion thereof curved laterally at their inner ends to moet acorresponding portion of an adjacent'spoke, a portion a't their outerends curved laterallyto form the juncture with the rim of the wheel, anda portion extending radially from the hub between the curved portions ofthe spokes.

2. A metal wheel consisting of a hollow hub, channeled spokes and a*rim, said spokes being tal'iered outwardly from the hub, and having aportion thereof curved laterally at their innerends to meet acorresponding portion of an adjacent spoke, and a portion at their outerends curved laterally to form the juncture with the rim of the wheel.

3. A metal wheell consisting` of a hollow hub, channeled spokes and arim, said spokes being tapered outwardly from' the hub, a portion -atthe outer ends thereof being; curved laterally to form the juncture withthe rim of the wheel, and a portion extending radially from the hubbetween the curved portions of the spokes. Y

4. A metal wheel consisting' of a hollow hub, spokes and a rim, saidspokes being of I-bea n1 formation in cross section and havingthe-flange portions thereof curved attheir innerends to'lneet theflanges of adjacent spokes7 and widened and curved. oppositely at theirouter ends to form the juncture with the rim of the wheel; the webportion of the hub being' spread to conform to the curvature of saidfianges. i

5 A wheel consisting of a hollow hub, I- beam spokes and oppositelydisposed rims joined together at their inner edges lby a series ofchannels extending longitudinally between the rinis, and by acorresponding series of cross bars disposed between said channels.

(5. A wheel consisting;- of a hollow hub, I- beam spokes and oppositelydisposed rims joinedtogether at their inner edges by a series ofchannelsv extending longitudinally between the rims. .f

7; A wheel consisting of a hollow hub, I- beam spokes and oppositelydisposed rims joined together at their inner edges by a series ofchannels extending longitudinally-between the rims; 'the flanges of thespokes beinagr spread 'apart andeurved loutwardly to merge with vsaidrims, and the web of the spokes being spread between said curvedportions and merfred with channels.

8. A wheel consisting of a hollow hub, I- 'beam spokes and oppositelydisposed rims joined togethe at their inner edgesby a se.v ries ofchannels extending longitudinally between theriins; the flanges of thespokes being spread apart and curvedoutwardly to n'ierge with said rims.

9. A wheel consisting of a hollow hub, spokes and rim,` said spokesbeing I-beam shaped in cross section and having the flanges thereofwidened adjacent the hub and rims and curved outwardly and the web'thereof spread between said curved portions. In testimony whereof, Iaffix my slgnature.
